Brueninghaus Hydromatik Rexroth A6VM Motor

1 Brueninghaus Hydromatik Rexroth a6vm Motor Hydraulic Variable Motor A6VM55, A6VM80, A6VM107, A6VM140, A6VM160, A6VM200, A6VM250. Features Variable Motor with an axial tapered piston rotary group of bent-axis design for hydrostatic drives in open and closed circuits For use in mobile and stationary application areas Series 6 The wide control range enables the variable Motor to satisfy the requirement for high speed Size Nominal pressure : 350 bar and high torque. Peak pressure : 400 bar The displacement is infinitely variable from Vg max to Vg min = 0. Open and closed circuits The output speed depends on the flow of the pump and the displacement of the Motor . The output torque increases with the pressure differential between the high and low pressure side and with increasing displacement.

2 Wide control range with hydrostatic transmission Wide selection of control devices Cost savings through elimination of gear shifts and possibility of using smaller pumps Compact, robust bearing system with long service life High power density Good starting characteristics Low moment of inertia Victory Hydraulic Pump Manufacturing Ordering Code / Standard Program A6V M / 63 W V . 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20.
